' NUT-HOLDER;

Specification of Letters Patent.

To all whom it may concern: i I

Be it known that I, WILMER M. WEBB, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Nut-Holders, of which the following is a specification.

One object of my invention is to provide a ply and at the same time of such nature as to not require the exertion of such force for its application as might break or injuriously strain the structure to which it is applied.

A further object'of the invention is to provide a novel form ofdevice for holding a nut to the body or any other portion of a lamp receptacle'or other fixture, which may be easily and quickly applied thereto without endangering or breaking the porcelain of which'such' fixture is made; y These objects and other advantageous ends I secure as hereinafter set forth, reference being bad to the accompanying drawings in which,

Figure l is a side elevation, partly in section, of a recepta le or socket showing my invention as-app led thereto; Fig. 2 is a fragmentary vertical section further ill'ustrating the construction and. use of my invention, and Fig. 3 is a perspective view of thenut holder itself.

While it is obvious that my improved nut holder or supporting device may be used on any desired object, I have found that it may be employed with great advantage for supporting nuts on lamp sockets or receptacles in such a position that they are at all times retained in positionready for the reception of thescrews whereby a cover plate may be held to or over such receptacle.

In Fig. 1 of the above drawings, 1 rep-,

resents awell known form of receptacle for an incandescent lamp, having on each side a laterally projecting lug 2, and each of these lugs is provided with a hole 3 for the reception of a screw 4 whereby the face plate or cover may be removably'held to said receptacle. This hole is preferably counter-sunk at its lower end, as indicated at 5, for the reception of' a nut 6 into which the screw 4 is threaded; the shape of the hole being such asto prevent the rotation "of the nut. .In order that the latter shallbe and both plate an with the receptacle, I provide the holding or retaining device shown in Fig. 3, which consists of aplate 7 having a central opening .8, preferably of such diameter as to loosely receive the screw 4. F rom-. opposite sides of the plate 7 project holding arms 9 whose extremities ,are bent so as toextend away from each other in, a line substantially at right anglestothe eneral'line of the arms, its arms are made of I Patented Dec.10,1912.

transported spring sheet-material so that when the extremities of said arms are bent toward/each other they tend to return to their original separated positions.

As shown in Fig. 1',the upper or outer 'end of the screw receiving hole 3 in each lug is provided with shallow. lateral recesses l1 and thereare likewise two oppositely placed lateral extensions 12 of each screw hole 3 tapered from the lower end thereof to the inner ends ofthe recesses 11. When therefore it is desired to assemble the parts of the device, a nut 6 is placed in each ofthe counter sunk holes or/recesses 5 of thereceptacle and thereafter one of the holding devices shown in Fig. 3 is. inserted tohold the nut in place, its arms 9 being entered in the tapered extensions 12 and then pushed inwardly until their extremities 10, after having been ,closely approached to each I other, finally-spring out into the recesses fll, so as to hook to the relatively sharp edges formed between said recesses and theextensions 12. Each nut 6 is then held in its recess 5 by the body of the holder and is preventedfrom rotating by reason of the square or irregular shape of'said recess 5 in which itis mounted, although even if saidrecesses were circular in form, the arms 9 would] serve the same function. The nut is thus prevented from falling out of its re cess since the ends '10 of the arms 9 very efli'ectually hold the body plate 7' close against it sothatat any time the screw 4 may be placed in the hole 3 and caused to enter the threaded openingv of the nut 6, which is vthusat all times held in position ready to receive said screw.

It will be noted that the edges between the laterally extending recesses 12 and the recesses 11 constitute shoulders for engagement with the hooked ends 10 of the arms 9,- so that where hitherto it has. been necessary to bend out the stiff, unresilient ends sunk recess; with a holding device for re nut, my nut holding device can quickly be sprung into place without requiring the exertion of any appreciable amount of force.

By this means, I have altogether avoided the loss heretofore invariably occurring by reason of breakage of the porcelain receptacle when the metalends were bent into the forms require'd'to hold the nut which was integral with them.

I claim: p 1.,The combination of a supporting struc turehaving a hole therein; a nut holding device mounted adjacent said hole andhaving arms engaging recesses in the structure; with a nut structure independent'of said device-and held thereby in line with thehole in the structure.

2.' The combination of a supporting structure having a hole therein and rccessesadjac'ent 'said hole; a nut holding device having bent arms extending into said recesses and provided with a perforated body portion; a nut supported by said-body portion in line with the hole inthe structure, and a screw mountedin the hole'and threaded iu the nut while passing loosely through the perforation of the holding device.

.3. The combination of a supporting structure having a counter. sunk recess at lone. end and two oppositely placed recesses at its other end; a nut mounted in said counter taining said nut in place consistingv of a. plate having arms extending into said op-- posite recesses.

4. The combination of a supporting structure having a hole therein provided withinwardly tapered recesses and shoulders adjacent the ends of said recesses, a nut mounted. with its openin substantially in line with the hole of sai structure; and a retaining device 'for holding the-nut in place the tapered recesses and rovided with bent ends'engagin .the shoul ers.

ture having a holetherein provided with inwardly taperedrecesses-and shoulders adjacent the ends 'of said recesses; a nut havmg its opening substantially. in line with the hole of said structure; with a retaining device for holding the nut in place consisting of a nut engaging plate and two arms extended ,therefrompassing through the tapered recesses and provided with bent counter sunk recess of irregular form in the the holding device, for receivino the nut.

6, As anew article of manuihcture a nut holding device consisting of a plate having a body portion and two hooked arms of spring material extendingin lines substantially at right angles thereto." .4

7. As a new article oft manufacture, a

relatively thin sheet material having spring arms extend' from its opposite sides in lines substantially at right angles to its plane; the extremities of said arms being bent away 1 from each other to form holding elements.

In'testimony whereq'f, Ihave signed my name to this specifica ion, in the-presence of two-subscribing wit esses.
